If your CamScanner app keeps crashing on your Android phone, the most common causes are corrupted app cache, outdated app versions, or insufficient device storage. You can usually fix this quickly by clearing the app cache, updating CamScanner through the Google Play Store, or restarting your phone.
Why Does CamScanner Keep Crashing on Android?
CamScanner is one of the most popular document-scanning apps for Android. However, like any heavy productivity app, it can sometimes freeze, force close, or refuse to open.
When you use CamScanner, the app relies heavily on your phone’s camera, processor, and storage. If your phone runs low on memory or if temporary files become corrupted during a heavy scan, the app may crash unexpectedly. Understanding why this happens helps you apply the right fix without losing important scanned documents.
Quick Troubleshooting Checklist
Before diving into advanced fixes, check these basics:
- Internet Connection: Ensure your Wi-Fi or mobile data is stable.
- Device Storage: Make sure your phone has at least 1GB of free storage space.
- OS Updates: Check if your Android system is up to date.
Step-by-Step Guide: How to Fix CamScanner Crashing
Follow these troubleshooting steps in order to get CamScanner working smoothly again.
Step 1: Force Stop the App
Sometimes, background glitches cause apps to malfunction.
- Open your Android Settings.
- Go to Apps > See all apps (or App Manager).
- Find and tap on CamScanner.
- Tap Force Stop and confirm. Try opening the app again.
Step 2: Clear App Cache and Data
Corrupted cache files are the #1 reason scanning apps crash.
- Go to Settings > Apps > CamScanner.
- Tap Storage & cache.
- Tap Clear Cache.
- Note: If the issue persists, return here and tap Clear Storage (warning: make sure your important scans are backed up to the cloud first, as this resets the app).
Step 3: Update CamScanner
Running an older version of the app on a newer Android operating system often leads to bugs and crashes.
- Open the Google Play Store.
- Search for CamScanner.
- If an Update button is available, tap it to install the latest version.
Step 4: Reinstall the App
If system files are permanently damaged, a fresh installation is best.
- Long-press the CamScanner icon and tap Uninstall.
- Open the Google Play Store and download the app fresh.
- Log back into your account to restore cloud-synced documents.

Frequently Asked Questions (FAQs)
1. Will I lose my scanned documents if I clear the CamScanner cache?
No. Clearing the cache only deletes temporary junk files. However, clearing storage or data may erase local documents that are not synced to the cloud.
2. Why does CamScanner crash specifically when I try to scan a document?
This usually happens when the app tries to access your camera hardware or process heavy image filters while your phone is low on RAM. Try closing other background apps before scanning.
3. Does uninstalling CamScanner delete my cloud documents?
No. If you were logged into a CamScanner account (using Google, Apple, or email), your documents stored in the cloud will safely reappear when you log back in.
4. How much free storage does CamScanner need to run properly?
While the app download is relatively small, it creates temporary image files during scanning. It is best to keep at least 1GB to 2GB of free space on your device.
5. Can a low battery cause CamScanner to force close?
Yes. Many Android phones enter a strict battery saver mode that restricts background processes and camera access, which can cause resource-heavy apps like CamScanner to crash.
6. Is there an alternative if CamScanner still won’t work?
If troubleshooting fails, you can temporarily use alternative document scanners available on the Google Play Store, such as Google Drive’s built-in scanner or Microsoft Lens, until the issue is resolved.
